Visionary's Perch (5E)

From publisher blurb: A 5e Compatible GM's Resource by Jacob W. Russell Far from the nearest shore, an ancient tower rises from the cold sea. Visitors who brave storm-lashed and pirate-filled waters to reach this remote island can gain a glimpse into the future or answers to their questions…for a price. The ancient cyclops seeress who dwells here, still watched over by the elves who conquered her people, requires a tribute from the penitents seeking her visions. Such prices may be designed simply to help fill the tedium of centuries in her gilded cage, or may in fact be a piece of a plan to rebuild her ancient empire; in any regard, they are non-negotiable.
